Watching the BBC News at One today. It has only been eight years, so if the BBC cannot get it right, what chance has the public?
Openreach are still part of BT Group, BT Group are the parent company, so I think you can forgive anyone for putting BT before it.
It is kinda confusing. Facebook was the parent company for Facebook for a while, Facebook was the parent company for WhatsApp and Instagram also, I thought that was pretty confusing until the parent group changed its name to Meta, now its Facebook by Meta, WhatsApp by Meta etc...
